Compute the sweep result of the smaller capsule with radius specified byGetValidPerchRadius(), and return true if the sweep contacts a valid walkable normal within InMaxFloorDist of InHit.ImpactPoint. This may be used to determine if the capsule can or cannot stay at the current location if perched on the edge of a small ledge or unwalkable surface. Note: Only returns a valid result if ShouldComputePerchResult returned true for the supplied hit value.
True if the current location is a valid spot at which to perch.
